Abstract

The invention discloses an intelligent active dust absorbing blackboard. The intelligent active dust absorbing blackboard comprises a dust sensor, a switch, a controller, a light warning device, a dust absorbing fan, a dust collection bag and a power source module. The dust sensor, the switch, the light warning device, the dust absorbing fan and the power source module are all connected to the controller, and the dust collecting bag is further arranged on the dust absorbing fan. Through the method, the intelligent active dust absorbing blackboard can well prevent chalk dust in a classroom from damaging the health of teachers and students.

Description

technical field [0001] The invention relates to the field of teaching appliances, in particular to an active dust-absorbing intelligent blackboard. Background technique [0002] Blackboard is the most used teaching tool in daily teaching. At present, the writing tool on blackboard is mainly chalk. No matter what kind of chalk, it will cause dust to fly in the process of writing and erasing, which seriously threatens the health of teachers and students. Today, with increasing attention to air dust pollution, while striving to develop fine dust chalk, a blackboard that can actively remove dust is needed. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an active dust-absorbing intelligent blackboard, which not only solves the situation that the dust concentration near the blackboard exceeds the standard in time, but also silently warns nearby personnel, and turns on the dust-absorbing fan to actively remove dust. ...
